I create 3 definitions for accounting flexfield and attach valuesets to them. However, when I compile them, the following error occurs. Pls help in determining what it is and how i can solve it.

APP-FND-00668: The data that defines the flexfield on this field may be inconsistent. Inform your system administrator that the function: FDFRKS could not find the structure definition for the flexfield specified by Application = &APPL, Code = GL# and Structure number = 52733 (APPID=101)

FDFBKS: REQUIRED constraint specified for the GL_ACCOUNT qualifier is not satisfied
